Cell transformation assay
WebThe first protocol for artificial transformation of E. coli was published by Mandel and Higa in 1970 [3]. The procedure showed increased permeability of the bacterial cells to DNA after treatment with calcium (Ca 2+) and brief exposure to an elevated temperature, known as heat shock.This method became the basis for chemical transformation.In 1983, … WebThe CytoSelect™ Cell Transformation Kits provide a robust system for screening oncogenes and cell transformation inhibitors.

WebIn the present study, we evaluated carcinogenic potential of PFOA using the cell transformation assay on SHE cells. The chemical was applied alone or in combination with a nontransformant concentration of benzo[a]pyrene (BaP, 0.4 μM) in order to detect PFOA ability to act as tumor initiator or tumor promoter. The results showed that PFOA ...
